Kelly said runners from 14 different states already have preregistered for the Durango Double. Numerous runners, he said, will double up with a trail race Saturday and a road race Sunday.

“We have more than ever before doing the big double,” Kelly said of the 50K trail run followed by a full 26.2-mile road marathon the next day.

“We have 65 (runners) in the big double,” Kelly said.

In all, Kelly said the road races will have about 200 participants.

The two trail races will feature about 150 participants, with additional registrations anticipated.

“We’ve had a nice run of registrations,” said Kelly, who added that the various running combinations over two days are ideal for running families. In fact, he said, the registrations for the road race indicate a field of 66-percent women.

The marathon and half-marathon distances are popular among women, Kelly said.

“We’ve got good traction there with the road races,” the race director said.

“The Women’s Resource Center has done a phenomenal job of getting volunteers for the Durango Double. It takes a ton of people to make this thing work.”

The Durango Double is sponsored by Animas Surgical Hospital, with the Women’s Resource Center as a beneficiary of the race weekend.

Additional volunteers for the races may call Liz Mora at the Women’s Resource Center at 247-1242, Kelly said. He said paperwork for the official USA Track and Field course certification has been filed.

And the courses are ready, Kelly said.

The 25K and 50K trail races Saturday will start and finish at Animas Surgical Hospital. The courses will use the Carbon Junction and Horse Gulch trail systems.

The races will start both days at 8 a.m.

Course maps are available online at durangodouble.com.

The road races Sunday, also starting at 8 a.m., will begin at Fort Lewis College. The road courses will descend from the college mesa and run past Animas Surgical Hospital where they will join the Animas River Trail.

The half-marathon course will have a turnaround near Walmart.

The full marathon will go to the end of the River Trail before crossing over the La Posta Road bridge. The course will go 3 miles out La Posta Road to a turnaround.

The runners will take a detour to Ska Brewing in Bodo Park before heading back to Durango on the River Trail.

The full marathon distance runners will go to the north end of the River Trail before turning around and running back to the finish line in downtown Durango at Buckley Park (12th and Main).

Packet pickup for runners will be available at Animas Surgical Hospital from 2 to 6 p.m. Friday and from 10 a.m. to 5 p.m. Saturday.
